Rare Discovery Shows Insects Perform Both Pollination and Seed Dispersal

The discovery of a unique case where the same insect species both pollinate a plant and distribute its seeds not only solves a long-standing botanical mystery. The Kobe University find also stresses the diverse roles insects play in our ecosystem.

Uncovering the Genetic Basis of Sex Determination in Amborella trichopoda

Although it is a complicated process, plant reproduction is essential to both ecological balance and the food chain. Some plants are hermaphrodites, some are either male or female, and some change sex during their lives.

Hormonal Control of Caste Determination in Ants

Most ants have two morphologically differentiated adult castes - queens and workers - each irreversibly specialized for either reproduction or nonreproductive altruism such as foraging, defense and care of maternal brood. Adult gynes (virgin queens) normally have higher body mass, wings and frontal eyes, as well as enlarged ovaries and a sperm storage organ.

A New Understanding of Dragonfly Adaptation to Climate Change

Temperature determines where species can live and if they are threatened by a warming climate. So, for a long time, biologists studied how heat tolerance affects survival. Yet, less is known about how thermal traits influence reproduction, which is directly linked to extinction risk.

Insights into the Formation of Nascent Membrane Structures in Yeast Sporulation

Sexual reproduction, a common mode of reproduction among numerous species, involves gametogenesis in which offspring are produced through fertilization, conjugation, or mating. In plants and animals, eggs and sperm differentiate from germ cells to form gametes.

COI1 Proteins in Maize Show Unexpected Functions for Crop Improvement

Maize (corn) is one of the most important staple crops in the world and has been extensively studied. Yet, many aspects of the genetic mechanisms regulating its growth and development remain unexplored.

Fruit Fly Study Reveals New Mechanism for Protein Production

Scientists from the University of California, Merced discovered a biological mechanism shared by numerous creatures through the use of fruit flies, which could have a significant influence on the comprehension of cancer and aging.

Inflammation-Induced Epigenetic Changes Limit Intestinal Stem Cell Regeneration

Researchers from the University of Michigan, Baylor College of Medicine, and other affiliated institutions have found that intestinal stem cells (ISCs) are permanently altered by inflammation in the gut, which limits the cells' capacity to repair the gut even after the inflammation has subsided.

Pesticide Exposure Strongly Correlated with Fewer Wild Bee Sightings

Whether you're strolling through a garden, wandering a park, or simply enjoying an open space in the United States, you're likely to notice bees buzzing about the flowers. While honeybees, imported from Europe in the 17th century to produce honey, are the most recognizable, they aren't the only bees at work. If you're a keen observer, you might spot some of the thousands of less familiar, native bee species that call these spaces home.

Study Reveals Strigolactones as Key Regulators of Tomato Flowering

In an article published in the journal PNAS, researchers at the University of São Paulo's Luiz de Queiroz College of Agriculture (ESALQ-USP) in Brazil describe for the first time how strigolactones, plant hormones discovered several decades ago, control flowering and fruiting in the tomato (Solanum lycopersicum). The findings of their study point to a new opportunity for management of fruiting time and could have a significant impact on total yields for this crop.
